The mill is powered by two 5500 hp D.C. motors. Nominal mill speed is 10.7 r.p.m. (78% critical) with a top speed of 11.3 r.p.m. The mill discharges through a grate with 3″ pebble ports onto a 14′ dia. x 13′ trommel screen with ¾" openings. On January 19, 1991 the mill was brought on line as a fully autogenous mill without pebble crushing.

Ball Mill Loading - Dry Milling - Paul O. Abbe
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...
